Related to the premise of:

Movie bore no resemblance that story.

Premise (very Crichton-like):  "Hey, let's take some chemosynthetic organisms that evolved near deep sea thermal vents under extreme pressure and heat and put them in a zero gravity environment with none of the environmental checks in place that regulated their growth.  Sound cool, huh?!?!"

Barfmaker: I thought we were going to defeat the ISS in 30 days.


It's been 8 months and all we've managed to do is take off an "I"

Now to the article, apparently bacteria have a difficult time absorbing nutrients and performing other actions in space. I wonder how this affects their ability to infect individuals.

That's like saying if you took animals and dumped them into an environment without the crushing concentrations of toxic, oxidizing waste products they live in now, their population would explode.

In reality, they'd suffocate. They need that toxic, oxidizing waste product (oxygen) to breathe.

All that heat and pressure and sulfur? That's a feature, not a bug. They need that stuff.

And that is why it is a science fiction novel ;-)

Regardless, it's a fun thought experiment.  We're built in some part due to the conditions in which we evolved.  Hence the real experiments they're doing up there.

Reminds me that I rented the new movie "Life" , the other day, OH MAN, what a stinker.  They found stupider astronauts than the ones from Prometheus AND Covenant. It was fun to see Ryan Reynolds get killed, though, but considering how much the movie sucked, I'd consider it a mercy.

I don;t hate Ryan or anything but that was a minor shocker to see him get offed so early and permanently,  Overall, I liked Life. The ending was the best, and the worst part.

I say we take off, nuke the site from orbit. Only way to be sure.

Too small of a target. Our targeting computers will never lock on and hit it. We need it to land on Earth and create a bigger target. THEN we can nuke it from orbit.

LIFE was a terrible  movie because the astronauts did dumb things only because the screenwriter needed them to do those things, not because that's what real astronauts would have done.

Xenobiologist starts poking and playing with "Calvin" like it's a toy, and  mission control says nothing.  Like, ever.  He accidentally "kills" it, and nobody calls a halt to review the experiment and protocols?

"all the radios are dead because the coolant is gone, creature drank it".
First, there would not have been any plumbing connecting the coolant loops to the air system of the hab modules. There is no reason for that plumbing to ever happen.
Second,
There is always at least one Soyuz docked at ISS; you coulda used the radio in THAT. Or the ARRL ham radio set, or one of the other, I dunno... (does quick check)...at least 6 radio transceivers on the station. Or the redundant ones in in each of the "escape pods".

Or there is: "the thing got out of it's box, seal the lab and purge the air in it and sorry doc, but  you're very likely contaminated now, you knew the job was dangerous when you took it".

Then there's" "we broke every CDC protocol in letting you out of that box to share our air and let whatever is on or in you mix with us."

And again: "The thing has been lured off the station and now is on/in my spacesuit: I'm going to kick away from the station and take the thing with me as we first freeze and then burn up together, saving the world and you guys.... name a school after me, kthnxbye." But no.

And of course, the really stupid idea that the thing can re-enter the station thru the inside of a rocket engine nozzle. Which in no way connects to anything inside the station's habitated areas.

There is using a flamethrower in a high-oxygen space station environment. No.

There's a Calvin outside the station, and another one spawns from the paralyzed leg tissue of the professor, and everyone conveniently forgets about the one outside from then on.

There is a guy jumping into a suit and decompressing an airlock without nitrogen purge pre-breathing and the co-actor even tells him this is risky - you'll get the bends and likely die or become incapacitated... "whatever, I do what I want".

NASA sends up a Soyuz to push the station out of Earth orbit... I don't think so - not enough  fuel.  Having it carry up a big-ass fusion bomb WOULD work, probably. That would have been my call.

Japanese astronaut wants to see his wife and new baby, is willing to risk killing them and everyone on Earth by bailing out in the Soyuz against protocol, instead of bravely staying to fight  or bravely sacrificing himself to save everyone. Hey, I guess anything is possible in human behavior, but astronauts are very carefully chosen and trained people - they would all be most likely to do the heroic thing and destroy themselves, or go down fighting, rather than run home. Sho's cultural background would only tend to reinforce that self-sacrifice. Again, sloppy-ass screenwriting, forcing bad decisions and crazy actions in order to get the cast from plot point A to B.  Cutting off their coms, wasting all their fuel, this is just bad, unimaginative storytelling. I really wanted my six bucks back by about the middle of the film.

They'll have to be pretty huge so the Coriolis effect doesn't have everyone in a constant state of debilitating nausea.

Not that I'm against massive space stations.... just people underestimate just how massive they would have to be. Really, REALLY huge. To be practical it would have to make what was in 2001 look tiny. Otherwise every time you stood up you'd puke your guts up.

Why not just have the space station on one end of a really long tether, and some mass at the other end (spent booster(s))? You could reel it in now and then for maintenance, etc...

Solves the mass problem and gives you a nice big arc so no one gets queasy.

If their metabolisms are significantly impaired, they may stop expressing the genes that result in the expression of pathogenic proteins.  Until there's a survival advantage due to the presence of hosts.
